Why teams connect SAP S/4HANA and Unleashed Software

Two ERPs, one set of facts: Stacksync keeps SAP S/4HANA and Unleashed Software consistent in real time, whether they split the business or one is replacing the other.

Companies run two ERPs for structural reasons: a two-tier setup with subsidiaries on lighter systems, an acquisition that brought its own stack, a split by function or region, or a migration that will take quarters. In all of these, some of the same organizations, people, and transactions exist in both systems, and keeping them aligned by hand is a standing tax on the back office.

Stacksync syncs Journal Entries, Customer / Supplier Roles, Production Orders, Business Partners in SAP S/4HANA with Warehouses, Stock Adjustments, Bills of Materials, Invoices in Unleashed Software bi-directionally and in real time, with field-level mapping across the two data models and conflict rules you define. A record changed in either system is reflected in the other within seconds, not at the next interface run.

Common use cases

  • Push closed-won CRM opportunities into S/4HANA as sales orders without manual re-keying.
  • Surface invoice and payment status from S/4HANA inside the CRM so account teams see open balances.
  • Keep Products and pricing aligned between Unleashed and accounting or PIM systems.
  • Mirror Purchase Orders and supplier data to a data warehouse for procurement reporting.

Migration in parallel

When one system is replacing the other, run both fully live during the transition and cut over without a data freeze.

Shared master data

Where both systems keep records of the same customers, suppliers, or organizations, a correction in either updates the other.

Split by function

Where one system is the people or finance suite and the other runs operations, the records both sides depend on, such as organizations, cost centers, and reference data, stay in agreement.
